Re: chasis strength

Subframe connectors are more than sufficient.

Re: chasis strength

Hello, the third gens have one of the weakest unibodies that gm has ever made. Our subframe connectors will stiffen the car up dramatically and if later down the road you put a 6 point in you can tie that into our connectors.

We offer two different connectors. SFC009 is for a factory style exhasust that runs down the passenger side. SFC008 is for a car with full length header. Both versions are weld in and are made from 2" x 2" .120 dom steel and will greatly increase the strength of the subframe. Here is a link to our site. If you have any questions please let me know.

Using that line of logic, ask your friends why they think that the new muscle cars, sports cars, etc, lots of which are at 350hp and up, come from the factory without a 6-pt cage.

You will find that stupidity will be the answer to your question.

Subframe connectors will definitely help stiffen up the chassis. Not sure why you would need a 6 pt cage in your car though.


There is an article a few years ago in a magazine where they added a whole bunch of suspension pieces (sfc's, springs, panahrd rod, etc) to a mighty third gen and then took it to the track. It did BETTER on the skid pad and cone speed test than an NSX and BMW and was neck and neck with more exotic cars.

If you're interested, PM me and I'll give you the modifications and details

Re: chasis strength

dont do a cage, just do sfc. Cages are not good for street cars. They are overkill and just give more contact areas for your head to slam into during an accident.

I'll try to scan the article and send it to the webmaster.

In the meantime here are the highlights...

Article: Zig Zag Part II (Chevy High Performance Oct 99)

Car: 91 Camaro Z28

Suspension parts: Hotchkis - stb, sfc, ph rod, lca, 1" lowering springs, 1" rear sway bar. Bilstein shocks. Stock 36mm front sway bar.

Alignment: Carter - positive 3 degrees...Camber - negative 1/4 to 3/4 degrees...Toe-in - 1/16"

Rims and tires: 17 x 9.5" front and rear TT II's with 275/40R-17 competition rubber (Yokohama A008RS II).

Results.......

91 Camaro 0.95 Gs (skidpad) 66.9 mph (Slalom)

99 Vette - .91 / 63.4
99 Ferrari 355 - .98 / 64.3
99 BMW 528s - .83 / 63.1
Lotus Esprit - .93 / 61
Acura NSX - .93 / 64

"The 0.95 skidpad digits are just a tick of the new Porsche Carrera 4, and the 66.9-mph Camaro number is 3 mph faster in the slalom."
